CHARLES ELBRIDGE GIBBS, OF ORANGE, MASSACHUSETTS.

WATER WHEEL GOVERNOR.

SI ECIFICATION forming part of Letters Patent No. 307,758, datedNovember 11, 188%.

Application filed May 90, W84.

To all whom it may concern;

Be it knownthat I, CHARLES ELBRIDGE GIBBS, of Orange, in the county ofFranklin, of the Commonwealth of Massachusetts, have invented a new anduseful Improvement in Water-\Vheel Governors; and I do hereby declarethe same to be described in the following specification and representedin the accompanying drawings, of which Figure l is a top view, Fig. 2 anend elevation, Fig. 3 a front elevation, and Fig. 4 a vertical medianand transverse section, of a governor containing my invention, thenature of which is defined in the claims hereinafter presented. Fig. 5is a vertical section of the machine taken through the main shaftlongitudinally thereof. Figs. 6 and 7 are hereinafter described.

In the said drawings, the frame for support ing the main operative partsof the machine is shown at A, there being arranged within it, as shown,and supported in suitable boxes a a, the main shaft B.

Fixed on a tubular shaft, 0, fitted to revolve on the main shaft B,there are a driving wheel or pulley, D, and a spurgear, c. The said gear0 engages with another and longer gear, d, fixed on another shaft, E,arranged as represented, and supported in boxes 0 c. There are to theshaft two eccentrics, ff, which stand in opposite directions relativelyto each other. The 3.1111Sf/ g of the collars h h of the said eccentricsare pivoted to two vibratory arms, F F, that turn on the main shaft B,near the outer sides of two gears, G G, fixed on such shaft.

To each arm F there are two pawls, h, to engage with the next adjacentgear G, there being between the two gears a sector, II, that turnsloosely on the shaft B, and by a bar, 03, jointed to it is connected tothe yoke is, that embraces the sleeve Z, adapted to slide vertically onan upright shaft, I. To a cross-head, m, fixed to the said shaft and tothe sleeve Z, there are jointed two sets of toggles or arms, a a, eachset at their connecting joint being provided with balls or weights 0 0,as shown. The said shaft I, cross-head m, sleeve Z, two sets of arms a,and their weights are what is usually termed a ball-governor.

On the shaft I there is fixed a bevel-gear,p,

to engage with another such gear, q, carried by the shaft E. Thedrivingpulley being revolved by an endless belt proceeding from a pulleyand the main or some other proper shaft of a mill, the ball-governorwill be re volved, the motion of the said governor being accelerated asthat of the pulley may be increased. As the velocity of revolution ofthe governor may increase, its balls or weights by centrifugal forcegenerated in them will be thrown outward from their vertical shaft I,and thereby will cause the aforesaid yoke to be raised on the saidshaft, whereby the sector H will be moved upward. The two sets of pawlsin the meantime will be reciprocated in opposite directions on theperiphery of the are of the sector. As the work to be done by thewatenwheel may increase, the gate of such wheel has to be opened more,the contrary taking place as the work to be done by the said wheel maydecrease.

The shaft B is to be properly applied to the gate by suitable gears ormechanism, such as will cause the gate to be raised when the said shaftis revolved one way, and depressed while the shaft may be turned in theopposite direction.

As the speed of rotation of the governor may increase, the sector willbe raised to cause the pawls in passing off it to turn the two gears G Gin a direction to effect a downward or closing movement of the gate. So,as the speed of rotation of the governor may decrease, a contrary resultwill followthat is, the gate will be raised.

A water wheel governor as hereinbefore described is not my invention, itbeing well known and in common use, and generally termed the SchofieldGovernor.

In carrying out my said invention I have combined with such a governor,first, a stop motion second, a friction wheel and brake and itsclamping-screw, and, third, a lever and a weight'adjustable thereon,said additions and the objects of them being thus described: Thefriction-wheel is shown at K as fixed on the shaftB concentrically andclasped peripherically by the brake L. This brakeis in two separateparts, 9' and 8, formed as shown, and pivoted at one end of each to theframe A. A screw, if, goes through one of such parts near its free endand screws into the other. On turning such screw one way the two partsof the brake will be drawn toward the wheel, so as to hold with frictionthe shaft from being by the weight of the gate turned backward duringthe retreat of either set of pawls on the sector. The screw of the brakeis to be set up just sufficiently to prevent, by :means of the frictionwheel and bra-k e, the gate from falling, so as to turn the shaft in amanner to revolve its gears while either set of the pawls may be inretreat on the sector, as it will not do to have any back movement orbacklash of the shaft during such retreat of the pawls.

The next part of the machine to be described is the stop-motion.

On the gate being fully open it becomes necessary to prevent thegovernor from acting to raise it higher; otherwise breakage of thegovernor or the gate or parts of the mechanism for operating the gatewould be liable to result. To this end I have the stop-motion, which isa mechanism that on the gate being fully open will cause the sector tohe raised into its median position, so that the sets of pawls will by itbe held out of action on the gears G G, while such sets of pawls may bereciprocated on the sector. An auxiliary sector, M, having its peripherynotched or providedwitha shoulder, as shown at a in Fig. 6,,which is anunder side view of such sector, extends downward from the hub of the A.sector H. Below the two gear-wheels G G is a horizontal shaft, N, havingon one end of it a gear, 1), to engage with a gear, w, fixed on theshaft B. quently derives its rotary motion from the shaft B through thetwo gears o and w. The shaft N is screw-threaded, as shown at w, and hason the screw'a nut, 7, suitably formed and adapted to a rail, 2, toslide thereon rectilinearly and longitudinally thereof. A front View ofthis nut is shown in Fig. 7. There is fulcrumed on the shaftN abentlever, 0, whose shorter arm, a, extends into the notch u of the sectorM. A pin, 1), adapted to the lever to slide transversely through it,bears at one end against the inner face of the nut and is forced up tosuch by a spiral spring, 0, encompassing the pin, and fastened to it andthe lever. Furthermore, near the other end of the said pin b thereprojects from'theshaftN an arm or dog, I. As the gate may rise the shaftN will be put in revolution in a manner to cause the screw 00 to movethe nut y forward on the rail :4. In so advancing, the nut will forcethe pin I) endwise toward the dog The shaft N conse- 1? until such dog,which will revolve with the the side of the pin. On this taking placethe dog by its action on the pin will press it upward, and therebycreate a movement of the lever 0 such as will cause it by its actionagainst the notched sector to move the latter to force the sector 1-1 upinto its median position, in which case the two sets of pawls inreciprocating on such sector will not act on the wheels G G to revolvethem. Thus it will be seen that with the stopmotion the shaft B will bestopped in its rotary motion on the gate being open to its extreme.Should the speed of the governor increase, the sector H will be moved soas to enable the pawls to turn the gears in a manner to effect adownward movement of the gate. A lever, B, fulcrumed toa post, S, andhaving its shorter arm pivoted to the yoke of the ball-governor, has itslonger arm provided with a weight, T, adjustable lengthwise on it. Thepurpose of this lever and weight is to counterbalance or overcome moreor less the gravitating power of the weights of the governor, in orderto cause such weights to move outwardly quicker by centrifugal force asthe speed of the main shaft of the mill may require from time to time.

I I claim- 1. The combination of the water-wheel governor, substantiallyas described, and a fric-- tion-wheel applied on its main shaft, with a.brakeand its clampingscrew adapted to such wheel and to the frame of thesaid governor, and to operate with the-wheel essentially and j for thepurpose as set forth.

3. The combination substantially as described, constituting thewater-wheel stop.- motion. it consisting of the gears 11 and w, shaft N,screw as, dog P, nut 3 rail 2, pin 2), spring 0, bent lever O, andnotched sector M, 110 arranged and applied essentially as set forth.
